Provided is a photosensitizer that can make a compound having a polymerizable group be efficiently cured by irradiation with an active energy ray. A photosensitizer comprising graphene,

Photosensitizer and active energy ray-curable composition

A light-modulating material of which the light transmittance can be controlled over a wide region from visible light to infrared light by voltage application is provided. The light-modulating material comprises a graphene-like carbon material having an aspect ratio of 3 or more and 330 or less.

Light-modulating material, light-modulating film, and light-modulating laminate

Provided is a new polycyclic aromatic hydrocarbon derivative. The polycyclic aromatic hydrocarbon derivative is a derivative of a polycyclic aromatic hydrocarbon having 6 or more aromatic rings and has a substituent represented by the following formula (1). (In the formula (1), Rand Rare carbon atoms of the aromatic rings in the polycyclic aromatic hydrocarbon, and Rto Rare carbon atoms of an aromatic ring or a heterocyclic ring in a group having the aromatic ring or the heterocyclic ring. n is 0 or 1, and m is the number of substituents.)
